Application filed January 1 whom may concern:

lle it known. ihnt I. PHILIPP Kos'mm, engilicc'r, e. c i log all Finn rt-on.tl1e-Mnin, in the Province of Hess i 111 and Kingdom of Prus sic. Gern'uinjv. llfi'VG invented certain new and usefu. improvements in Processes for {he Production, of Gas from Bituminous Fuels in Intermittent Operation of which lho l flllUl ilig :1 sp cificntion.

This invention relates .io n process for the 'u-mluclioo oi? Qjus from bituminous fuels, and has coi'obiimtion of two oz? its ob ect il lmoivn methods of gas production into s ngle moce it of these processes continuous gen ntor method. In this. em and air are driven through the producer chamber continuously and at the some Lillie, so that the mess of coal caused to glow and the steamis decomposed simulh ieonsly. No Water gas is produced by ti method but a gas which contains the products; of comlmstion fox-med by the burnii'ic' oil the coal. This gas is very impure and 2-5 uusetis'hicioi'y for most purposes. The second of 'l'hese processes known as the intermilieut water gas method. 1 n this case, the I flown hot. by injected air, and only holbhisl. and air have been cut orf,

blown in. By this method the nbusdon may be separately :id only pure Wllikl' gas posses sicihod however somewl'mt T. elf f as on a non-bituminous con'ibusnible can be used.

1 methods explained in brief above, so that I may secure an almost pure 'nici" gas from a hitumimius combustible. "Vith this object i I make use of the intermittent cper nlion. method, by blowing air into the producer clnmhcr dozing the hobblast and conv is reveyling to pro Since it is a very small quenh'i'tler period in order .ble mess plowing, it will .7 h amount of the '1 pass oil with only of the German Empire, residl. iui'posc "co use a. combination of the two ailuctiog away the products of combustion as 1h lil in the second period 'ii z itenicd Nov. 1%, 19'35.

difference between the gas produced by my method and pure Water gas produced by the usual intermittent process. 1 have thus been able to use a bituminous fuel for producing a pure by means of a, suitable process, without melting a generator gas of low heating value.

A further characteristic of the present process is the injection of the air during the gassing period at; the point where the already coked mass and the combustible mat ter meet.

The accompanying drawings illustrate one form of apparatus suitable for use with my process.

In said drawings Figure 1 shows the posi tion of the mechanism during the hot blast, and 2 shows the same during the gassing; aeriod.

The letter (1. denotes the fuel feed opening, 5 the valve for the gas conduit, 0 21, Water seal, and (Z the gas conduit leading from the producer chamber to the seal.

6 is enozzle for the introduction of steam, f the ports for fihe hot'air blast, g the chimney, h the connecting channel between the chimney and producer chamber, 2' the damper for the chimney, and 7c and 'm the valves for closing the gas channel.

Z is a hand lever, connected to the damper i by a. rod 0; with the valve Z) by a rod '7 and with the slide valve 70 and valve m by rod (7; 0' is the handle to operate the steam nozzle 0 and s is the handle to operate the air nozzle 7".

Fig. 1 shows the position of the mochanism during the heating blast. The hand lever is thrown up thereby opening the chimney damper by means of the rod 0, and the valves is and m by means of the rod (7. The steam nozzle 6 andthe air port 7 are at ihe sometime closed by means of the handles r and 3. Air from the hot blast how liows through the upper portion of the producer chm'nber, ciiculates through the com bustible mess therein, and out of the chimney ihrough the channel 12. and damper z.

.Vhen ihe fuel is sufi'iciently hented the handle 3 depressed, thereby closing valves 2, 1b, and m. The steam valves and the air port f we then 0 led (see Fig. 2). The steam llo'ivs upvierilly through the bed of fuel, and a small quantity of air, just enough to keep the mass of combustible matter glowing, is injected through the air ports f, which are located substantially at the point where the coked and uncoked material meet. In this manner the upper surface of the coal is distilled and begins to form gas, which t0- gether with the gaseous products, are drawn outwardly through the channel d and seal 0, into any suitable storage tank.

I claim:

1. A process for the production of gas, consisting in heating a bed of fuel by a down blast, shutting off said blast and passing air and steam upwardly through the heated fuel whereby the steam is decomposed and gas is formed.

2. A process for the production of gas, consisting in heating a bed of fuel by a down blast, shuttingoff said blast and passing steam upwardly through the bed of fuel and introducing into the fuel suflicient air to support combustion, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses. PHILIPP KOSTER. Witnesses:
